摘要
Pre-Hispanic goldsmiths developed original techniques to manufacture and to gild ornaments and artifacts. Gold metallurgy in ancient America was mainly a surface technology. Surface studies of artifacts from various regions of pre-Hispanic South America were carried our using a 2 MeV proton microbeam (10 mu m diameter). Several regions of the artifacts were scanned: RBS and PIXE were used simultaneously to determine the elemental composition and to characterize the homogeneity in depth and at the surface. Complementary information is provided from previous analyses using a macrobeam. Outstanding aspects about the metallurgical processes involved in the gilding of the artifacts have been established.
